Flying into the eye of the storm

29.09.2004

While most of us watched this summer’s violent and destructive storms on TV from the comfort of our sofas, a team of researchers from across the UK, including University of Leeds scientists Alan Blyth, Barbara Brooks and Lindsay Bennett, took to the skies in specially equipped planes to study their origins.

The convective storm which caused flooding in Boscastle with 75mm of rain in two hours, is recognisable as bubbly cumulous cloud often seen in the UK. The research team from the school of earth and environment hope their observations will improve computer models used to predict these storms.

This summer’s monitoring was a pilot project in preparation for a full study next year, when the team will use radars, a network of automatic weather stations and aircraft to measure winds, temperature and humidity. The team will wait, with equipment ready, to catch the storms forming from June to August.

Project leader Dr Blyth said: “A research model under development at the Met Office has had some success in predicting the location and intensity of thunderstorms a few hours ahead, but improving the accuracy and reliability remains a difficult challenge.” The Natural Environment Research Council (NERC) funded Convective Storm Initiation Project (CSIP) includes the universities of Leeds, Reading, Salford, Essex, Bath, Manchester and the Met Office.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.

It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.

One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
